Switch to RTL using a stick other than the "flight modes" stick

ArduPlane Plane 4.5

Good afternoon,
The configuration is: ASW 28 motor glider with FC Matek H743 Wing V3 with Ardupilot 4.5.2., GNSS Matek M10Q-5883, radio control FrSky Taranis QX7 access.
Is it possible to switch to the “RTL” flight mode using a different stick than the one used for the “flight modes”?
Thanks

See auxiliary functions.

RCx_OPTION,4 - x being whatever RC channel you want to use.

One thing to remember is that Ardupilot will switch modes based on the last mode command it got. So if you set a switch to RTL and then change the other mode switch to FBWA for example, the physical RTL switch will still appear to be in the RTL position. You would need to cycle the switch low then high again to get back to RTL.
